This paper addresses the generation of spectrally pure sinewaves by combining the feedback structure of a Σ∆ loop with digital cancellation of unwanted spectral components in the output signal. In particular, the non-linearities of the in-loop Digital to Analog Converter (DAC) are compensated by applying a digital pre-distortion to the DAC input, and the feedback architecture is used to enhance...

Sir, An important though rare side effect of reconstruction surgery in oral cavity is persistent hair growth in the recipient site due to intact hair follicles.[1] Hair growth in the transplanted site may be due to the dominant nature of the underlying skin.[2] A 40‐year‐old male came to the dermatology outpatient department with a complaint of excessive hair growth in the oral cavity 2 months ...

BACKGROUND Occupational exposures to ultrafine particles in the plume generated during laser hair removal procedures, the most commonly performed light based cosmetic procedure, have not been thoroughly characterized. Acute and chronic exposures to ambient ultrafine particles have been associated with a number of negative respiratory and cardiovascular health effects. Thus, the aim of this stud...

Many state-of-the-art human face digitizing techniques or commercial 3D face scanners output dense facial triangle mesh surfaces. Most of these meshes contain some unwanted outliers, irregular boundaries, or some other extraneous parts, for instance hair, shoulders ∗ Corresponding author.

Personal goals are difficult to achieve and healthy habits are not as simple to maintain as people would like to. Often, humans look for help to change unwanted behavior. Technology could help us to overcome the daily struggle faced during the search for behavior improvement. The Persuasive Mirror is an example of how computerize persuasion, in the form of visual feedback, could give the needed...

Background and Objective: Alexandrite and diode lasers are commonly used for hair removal. To date, the available spot sizes and repetition rates are defining factors in terms of penetration depth, treatment speed, and efficacy. Still, larger treatment areas and faster systems are desirable. To compare the efficacy, tolerability, and subject satisfaction of a continuously linear-scanning 808nm ...

The paper focuses on solving the problem of hair removal in dermatology applications. The proposed hair removal algorithm is based on Gabor filtering and PDE-based image reconstruction. It also includes the edge sharpening stage using a new warping algorithm. The idea of warping is to move pixels from the neighborhood of the blurred edge closer to the edge. The proposed technique preserves the ...

Background: Arsenic toxicity as a result of consumption of hair removal agent has been rarely seen in last few years in comparison with the past. Case Presentation: In this case report, we presented a middle age woman referred to medical toxicology department due to epigastric pain and diarrhea following ingestion of hair removal agent. Urinary test for arsenic was positive. ECG changes and ele...
